Heavy lift stage of BassGas MLE completed

AWE Limited (ASX: AWE) has been advised by the Operator of the BassGas Project, Origin Energy Limited, that the heavy lift stage (Phase 1b) of the Bass Gas Mid Life Enhancement (MLE) project has been completed successfully.
In good weather conditions the heavy lift crane vessel, the "Sapura Acergy 3000", successfully installed the gas compression and condensate pumping modules onto the Yolla platform. Both lifts were performed as planned, safely and without incident, and the crane vessel has been released.
Tie-in and commissioning of the modules is scheduled to commence in mid-2015, after the planned development drilling activity is completed. The modules are not critical to current operating requirements and are expected to be commissioned in FY 2016-17.
The BassGas asset has been shut-in since 24th November for planned maintenance and facilities integrity testing and the compressor installation was integrated into this shut-in period. BassGas is due to recommence production in late December and will remain in operation until development drilling activity commences later in the first quarter of 2015.

AWE's Managing Director, Mr Bruce Clement, said that the successful completion of the heavy lift stage was a great achievement for the MLE Project Team and a major milestone for the BassGas Joint Venture.

"BassGas is one of AWE's cornerstone assets and the MLE project is designed to ensure we can produce from the Yolla field well into the next decade.
"Minimising shut-in time by completing the heavy lift activities during a period of planned maintenance and facilities integrity testing is an efficient use of resources and the result of good planning and preparation.
"We are now focused on the final stage of the MLE project, which comprises the drilling of two development wells, commencing in early 2015. These wells should increase production from BassGas to between 60-70 TJ per day, up from the 40 TJ per day average achieved over the September quarter," Clement said.
